15.2.2.14 GPL Base Address Register 0 (GPLBAR0)
The
GPL base address register 0 is provided to allow access to local memory space. This register
is closely tied to PIBAR0 and PIWAR0 in the CSR memory space. A write to GPL base address
register 0 also causes a change in the base address bits that are not masked according to the IWS
field of PIWAR0 in PIBAR0. Note that this write operation does not change the bits that are
masked by the IWS field. For read operations, these masked bits always return zeros. Table
15-16 shows the GPLBAR0 bit fields.
